Yes, I can definitely do that. I was tempted to put more bleach in this morning when I found it was only at 22. I'm willing to put bleach in 2 or even 3 times a day if necessary to get rid of any potential algae. Once I've got it at 30, and can maintain that level, how many days do I keep it there? I assume it's safe for me to get in the water to vacuum it, etc. at 30, correct? I think it just has the potential to make clothing fade at that level.
